To solve the problem, we will analyze the two cases separately. We will use the mirror formula and the magnification formula for a convex mirror. ### Given Data: - Radius of curvature (R) = 15 cm - Focal length (F) = R/2 = 15/2 = 7.5 cm (positive for convex mirrors) - Object distances (U): - Case (i): U = -10 cm - Case (ii): U = -5 cm ...
